Ultrasound-modulated electric machining and then the dynamic properties of the vibrating tool with system is analyzed through the method of dynamic analysis and without the load or not is discussed. Numerical simulation results are compared with the theoretical calculated value, the results show that the higher precision could be obtained while using the method of finite element analysis in the area of ultrasonic specialty. The rationality of the optimization design for this system is verified by using the method of ANSYS parametric optimization design and optimizing the ultrasonic vibration system and the system processing test; the technical advantages of ultrasound-modulated electrolytic machining in difficult-to-process materials and special-shaped surface processing are proved through microstructure ultrasonic compound electrolytic machining tests.
